UNITED STATES STINE L. JONES, OF BATON ROUGE, LOUISIANA.

RAILROAD-CROSSING GATE.

Application filed March 19, 1921.

To all whom it may concern:

Be it known that I, STINE L. Jones, a citizen of the United States,residing at Baton Rouge, in the parish of East Baton Rouge and State ofLouisiana, have invented new and useful Improvements in Railroad-Crossing Gates, of which the following is a specification.

This invention relates to railroad devices, particularly to crossinggates, and has for its object the provision of a novel mechanicallyoperated gate lowered at the crossing automatically upon the approach ofa train.

An important object is the provision of a device of this character whichrequires ab solutely no manual manipulation whatever, the lowering ofthe gates being effected by movement of a train engaging member andraising of the gates being effected by spring action.

Another object is the provision of a device of this character in whichthe crossing gate is formed as an arm carrying a plurality of flexiblemembers upon which are hung bells which will be jingled as the trainpasses over the operating device so as to effectually apprise personsthat a train is approaching.

An additional object is the provision of a device of this characterwhich will be simple and inexpensive in manufacture, highly eiiicient inuse, durable in service, and a general improvement in the art.

\Vith the above and other objects and advantages in view, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawings inwhich- Figure 1 is a side elevation of my device complete,

Fig. 2 is a plan View,

Fig. 3 is a longitudinal sectional view through the special rail on alarger scale,

Fig. 4 is a plan view thereof, the underlying parts being shown bydotted lines,

Fig. 5 is a cross sectional view on the line 5 of Fig. 4e, and

Fig. 6 is a cross sectional view on the line 6-6 of Fig. 4.

Referring more particularly to the drawings, the letter A designates atrackway and B designates a crossing. In carrying out my invention Iprovide a specially constructed rail 10 interposed in one of theordinary rails and comprising an elongated body 11 formed with alongitudinally extending Specification of Letters Patent.

groove 12 for the passage of the flanges of the wheels at one side of atrain, the treads of the wheels passing over the body itself. Thisspecial rail member is formed with a trapezoidal recess 13 and has itslower surface formed with a semi-cylindrical recess 14-. I

Disposed beneath the rail section 10 is a casting 15 which includes asaddle portion 16 secured to the bottom of the rail section and thissaddle portion is formed with a central hole 17 and two pair of sockets18. This casting 15 further includes an arm 19 extending laterallybeyond the rail and formed with a channel guide 20. The upper surface ofthis casting 15 is formed with a plu ality oi alined semi-circularrecesses 21 which are complementary to the recesses 1% and whichcooperate therewith to form bearings. The projecting portion of thiscasting 15 is formed with a pair of semi-circular recesses I Securedupon the projecting portion of the casting is a cap member 23 having achannel guide 24 complementary to the channel 20. This cap is alsoformed on its underside with semi-cylindrical recesses 25 which arecomplementary to the recesses 92 and which define bearings.

Journaled through the recesses 1i and 21 and and 25, is a shaft 26 whichcarries at one end a small pinion 27 and near its other end a largerpinion 28 located within the mating channels 20 and 24.

Disposed within the recess 13 of the rail is an operating member formedas a shoe 29 from the underside of which extends a rack 30 slidablethrough the hole 17 and meshing with the pinion 27. A plurality of coilsprings 31 fit within the sockets 1S and engage against the inside ofthe shoe 29 for resiliently opposing downward movement of the shoe andfor holding the shoe normally elevated in engagement with the inclinedsides of the recess 13.

Located at some point near the crossing is a supporting arm 32 whichcarries upstanding cars 33 between which is journaled a lever arm 34-having its lower end formed as a segmental gear 35 and having its upperend formed as an upwardly inclined arm 36 adapted to extend across thecrossing. Depending from this arm 36 are flexible members 37 from whichare suspended bells 38.

Slidable along the bottom of the opening between the cars 33 and throughthe mating channels 20 and 24, is a longitudinally movable bar 39 whichis formed at one end with rack teeth 40 meshing with the segmental gear35 and formed at its other end with rack teeth 41 meshing with thepinion 28.

Ordinarily the shoe 29 is in elevated posi-' shaft 26 and gear 28 andthis will result in longitudinal movement of the bar 89. The movement ofthe bar 39 will swing the lever 34Q and move the arm 36 downwardly atthe crossing. As the shoe 29 is spring-pressed upwardly it will vibrateup and down as the successive wheels of the train pass over it and thisagitation will be imparted to the arm 36 and will cause a continuousjingling of the bells 38 so as to warn all persons near that a train isapproaching. After the train has passed by the springs 31 will operateto return the parts to normal position.

While I have shown and described the preferred embodiment of myinvention, it is of course to be understood that I reserve the right tomake such changes in the form, construction, and arrangement of parts aswill not depart from the spirit of the invention or the scope of thesubjoined claims.

Having thus described my invention, I claim:

1. In a trackway, a depressible shoe engageable by the wheels ofa trainwhereby to be moved downwardly, springs normally urging said shoeupwardly, a rack depending from said shoe, a shaft, a pinion on saidshaft meshing with said rack, a second pinion on said shaft, a leverpivoted adjacent a crossing and having an inclined arm serving as agate, a segmental gear on said lever, and a longitudinally slidable barhaving its ends formed as racks, one rack engaging the second named gearand the other engaging said segmental gear.

2. In a. trackway, a depressible shoe engageable by the wheels of atrain wherebyto be moved downwardly, springs normally urging said shoeupwardly, a rack depending from said shoe, a shaft, a pinion on saidshaft meshing with said rack, a second pinion on said shaft, a leverpivoted adjacent a crossing and having an inclined arm serving as agate, a segmental gear on said lever, a longitudinally slidalole barhaving its ends formed as racks, one rack engaging the sec ondnarned'gear and the other engaging said segmental gear, and a pluralityof bells flexibly suspendedfrom said gate arm.

3. In atrackway, a rail section interposed in one of the track rails andformed with a recess, a shoe Within said recess normally projecting intothe path of travel of the treads of the wheel of a train, a pivotedlever adjacent a crossing to be protected having one end serving as agate and having the other end provided with a segmental gear, alongitudinally movable member having one end formed with rack teethengaging said segmental gear and having its other end provided with rackteeth, a supporting member extending laterally from said rail sectionformed with a channel guide, a shaft journaled transversely of saidtrack section and said lateral support, a pinion on said shaft withinthe channel meshing with the second named set of rack teeth, a secondpinion on said shaft, and a rack depending from said shoe and engagingsaid last named pinion.

In testimony whereof I affix my si nature.

STINE L. Jo ivEs.
